Hello Praveen,

Try the following code snippet.

ASPX:

<Columns>
            <telerik:GridDropDownColumn UniqueName="Dropdown" DataSourceID="SqlDataSource1" DataField="CustomerID" ListTextField="CustomerID" .. >
           </telerik:GridDropDownColumn>

CS:

    protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
        foreach (GridColumn col in RadGrid1.Columns)
        {
            if (col.ColumnType == "GridDropDownColumn" && col.UniqueName == "Dropdown")
            {
                if (e.CommandName == RadGrid.EditCommandName)
                {
                    (col as GridDropDownColumn).ReadOnly = true;
                    col.Visible = false;
                }
                else
                {
                    (col as GridDropDownColumn).ReadOnly = false;
                    col.Visible = true;
                }
            }
        }
    }

Hello Praveen,

To populate the combobox when the DropDownColumn is in insert mode, you can try out the following code:
c#:

 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridEditFormInsertItem && e.Item.OwnerTableView.IsItemInserted)
        {
            // Replace GridEditFormInsertItem with GridDataInsertItem if EditMode="InPlace"
            GridEditFormInsertItem insertItem = (GridEditFormInsertItem)e.Item;
            RadComboBox combo = (RadComboBox)insertItem["GridDropDownColumnUniqueName"].Controls[0];
            combo.DataSource = dt;
            combo.DataTextField = "Year";
            combo.DataValueField = "Year";
            combo.DataBind();
        }
    }

Thanks
Princy.
